Description

Alarms

Shows alarms of different severities in the last 7 days. After you click the number next to an alarm severity, the Alarm Rules page is displayed, showing all alarm rules of the severity.

Resources

Shows the vCPU usage, memory usage, storage usage, and disk IOPS of your instance.

Key Performance Metrics

Shows vCPU utilization & slow query logs, connections, memory utilization, and disk reads/writes of your instance in the last hour.

Health

Shows the health status of your instance based on operational data analytics and intelligent algorithms.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click in the upper left corner of the page and choose Databases > Relational Database Service.
  4. On the Instances page, click the DB instance name.
  5. In the navigation pane, choose DBA Assistant > Real-Time Diagnosis.
  6. On the Dashboard page, view the status of your instance.

    • In the Alarms area, view alarm information of your instance. To view alarm details, click the number next to an alarm severity.

      If attention needs to be paid to specific metrics such as CPU usage, storage space usage, and connection usage, you can create alarm rules and configure alarm policies for these metrics.

      For example, if you want to pay special attention to session traffic for new services, you can configure an alarm policy for connection usage by modifying the alarm rule of your instance. For details about how to modify an alarm rule, see Modifying an Alarm Rule.
